Biosensor? Answered

I want to make a biosensor of for glucose measurement. The aim is to develop a method for blood glucose measurement by measuring the impedance of glucose solution of various concentration. Suggest how can I measure impedance of a glucose solution and study variation of impedance with the concetration

Blood Glucose testers work by analysing the change in resistence over a fixed time of a fixed size sample impregnated with an enzyme that oxidises glucose at a known rate.

Unfortunately, simply measuring the resistance without the enzyme is not likely to work.

Do you mean impedance or resistance?

Impedance =essentially resistance to achieve

You need to experiment to see what sort of range your getting.

I would expect you will need to amplify the signal any way using an open amp . But the sensor needs to be little other than 2probes
